Have an old Sprint phone laying around that could be put to good use with free talk, text and data? FreedomPop is now expanding its wireless service, allowing customers to bring their own devices.Engadget reported Tuesday that FreedomPop has expanded its offer of free wireless service to now include any compatible Sprint phone capable of CDMA plus LTE or WiMAX, without the need to purchase a handset.

FreedomPop offers three tiers of wireless service: A free Basic plan, with 200 voice minutes, 500 texts; $7.99 per month Premium with 500 voice minutes, unlimited texts; and $10.99 per month Unlimited, with a free 30-day trial. Each plan also comes with 500MB of 3G/4G data, and additional megabytes can be added for 2.5 cents each.9to5Mac confirmed that the iPhone will indeed be included in FreedomPop's bring your own device plan, but it looks like you'll have to use that link to access the offer directly, since it wasn't showing up at the regular phone link above quite yet.

However, for those in need of a compatible handset, FreedomPop is currently offering the Android-powered HTC Evo 4G for $99 contract-free -- an even older smartphone than the company's previous HTC Evo Design offer, which apparently sold out immediately earlier this year.
